Papillary Adenocarcinoma in Thyroid, Lung, and Other Organs
By Raveena M Prakash
Papillary adenocarcinoma is a specific subtype known for its distinctive cell patterns and behavior. It is most commonly found in the thyroid, while papillary adenocarcinoma can also occur in various organs, including the lungs, breast, ovaries, kidneys, pancreas, and other organs. Papillary thyroid carcinoma (PTC) is the most frequent type of thyroid malignancy.
In this blog, we’ll discover more about this cancer’s nature and its diagnosis and treatment across multiple organs that can help in early detection and improved treatment outcomes.
What is Papillary Adenocarcinoma?
Papillary adenocarcinoma is a type of cancer that develops in the glandular cells, which are often responsible for secreting some substances such as hormones, enzymes, and mucus. The term "papillary" often refers to the appearance of the cancerous growth, which forms finger-like projections also known as ‘papillae’ under a microscope. These appearances are considered the key features of this rare type of cancer, which helps the pathologist to identify the cancerous tissue.
Papillary Adenocarcinoma in the Thyroid
The thyroid is the most common site for developing papillary thyroid carcinoma (PTC). In fact, 80% of thyroid cancers are papillary in nature. The thyroid is a butterfly- gland located at the front of the neck, which is highly responsible for producing the hormones which regulate metabolism, growth and development.
Symptoms and Diagnosis
The papillary adenocarcinoma generally tends to grow slowly and might not cause symptoms for many years.
When symptoms starts to appear, some of these may include:
- A lump or nodule in the neck
- Hoarseness or voice changes
- Difficulty swallowing or breathing
- Neck pain
The diagnosis can be made through a combination of physical examinations and blood tests to measure thyroid function. Additionally, imaging tests such as ultrasound, CT scans, and a fine needle aspiration biopsy are used to confirm the presence of cancer cells.
Prognosis and Treatment
The prognosis for papillary thyroid cancer is generally favorable, especially if caught early. The five year survival rate for localized papillary thyroid cancer is around 99%. There are some treatments that may include:
- Surgical removal of a part of the thyroid or all of the thyroid (thyroidectomy)
- Radioactive iodine therapy to eliminate any remaining cancer cells
- Thyroid hormone replacement to maintain normal metabolism if the thyroid is removed
Papillary Adenocarcinoma in the Lungs
While these types of cancers are more commonly associated with the thyroid, it can also occur in the lungs, particularly as a subtype of lung adenocarcinoma. Lung adenocarcinomas are the most common form of non-small cell lung cancer (NSCLC). These types of carcinoma of the lungs often refers to a particular pattern of growth in these tumors, characterized by papillary structures.
Symptoms and diagnosis
Symptoms of lung adenocarcinoma are often subtle and can include:
- Persistent cough
- Shortness of breath
- Chest pain or discomfort
- Unexplained weight loss
- Hemoptysis (coughing up blood)
Diagnosis involves imaging tests such as chest X-rays, CT scans, and biopsies to analyze the tumor. When the carcinoma is suspected, a detailed pathological examination of the tumor can confirm the tumor.
Prognosis and Treatment
The prognosis for lung papillary adenocarcinoma is variable and depends on factors such as the stage at diagnosis and the overall health of the patient. Early-stage papillary adenocarcinoma can be treated effectively with:
- Surgical resection (removal of the tumor)
- Chemotherapy and radiation therapy for more advanced cancer cases
- Targeted therapies and immunotherapy may be used in specific cases, depending on the genetic makeup of the tumor.
Papillary Adenocarcinoma in other organs
This is a type of cancer that can occur in glandular cells throughout the body. It can also affect various organs, including the kidneys, breast, pancreas, gastrointestinal tract, and ovaries. Each of these organs presents its own unique challenges for diagnosis and treatment.
In the Kidneys
Carcinoma is a form of renal cell carcinoma. It typically presents as an asymptomatic mass in the kidney and is diagnosed with imaging like ultrasound or CT scans. The treatment often involves surgery and, in some cases, targeted therapies.
In the breasts
While adenocarcinoma in the breast is a rare form of cancer. It tends to present as a painless lump in the breast and is diagnosed via mammography, ultrasound, and biopsy; treatment may involve surgery, radiation, and hormone therapy.
In the gastrointestinal tract
In the gastrointestinal system, a papillary adenocarcinoma can develop in the esophagus, stomach, or colon. These types of cancers can often grow slowly, and symptoms may not appear until the disease has advanced. Treatment might usually involve surgery, chemotherapy, and radiation therapy.
In the ovaries
An ovarian papillary adenocarcinoma is rare, but it can be a type of serious ovarian cancer. Symptoms may include bloating, pelvic pain, and changes in menstrual cycles. Treatment often includes surgery, chemotherapy, and, in some cases, targeted therapies.
Consult Today
Papillary adenocarcinoma is a slow-growing cancer in many cases. It can still pose a significant health risk if not diagnosed and treated early. It can also develop in the thyroid, lungs, or other organs. Early detection through cancer screenings, paying more attention to symptoms, and advanced diagnostic tools are key to managing the disease effectively.
